title: Development and validation of the mindfulness-based interventions - teaching assessment criteria (MBI:TAC).
abstract: BACKGROUND
  The assessment of intervention integrity is essential in psychotherapeutic intervention outcome research and psychotherapist training. There has been little attention given to it in mindfulness-based interventions research, training programs, and practice.
  
  
  OBJECTIVE
  To address this, the Mindfulness-Based Interventions: Teaching Assessment Criteria (MBI:TAC) was developed. This article describes the MBI:TAC and its development and presents initial data on reliability and validity.
  
  
  METHODS
  Sixteen assessors from three centers evaluated teaching integrity of 43 teachers using the MBI:TAC.
  
  
  RESULTS
  Internal consistency (α = .94) and interrater reliability (overall intraclass correlation coefficient = .81; range = .60-.81) were high. Face and content validity were established through the MBI:TAC development process. Data on construct validity were acceptable.
  
  
  CONCLUSIONS
  Initial data indicate that the MBI:TAC is a reliable and valid tool. It can be used in Mindfulness-Based Stress Reduction/Mindfulness-Based Cognitive Therapy outcome evaluation research, training and pragmatic practice settings, and in research to assess the impact of teaching integrity on participant outcome.
